HOSE-NOZZLE ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No.291,107, dated January1, 1884.

Application filed February 16, 1883. (No model.)

To wZZ whom it may concern Be it known that I, RICHARD F. ToBIN, ofSouth Boston, county of Suffolk, Stat-e of Massachusetts, have inventedan Improvement in Hose-Nozzle Attachments, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

My invention consists in the improved deflecting-plate hereinafter moreparticularly set forth and claimed.

In the drawings referred to, Figure 1 is a longitudinal section of aportion of a hosenozzle and attachment embodying this invention, andFig. 2 a plan View of the face of the distributing-disk, itssupportingarms being shown in section.

The hose-nozzle, a, of any usual construction, is shown as threadedaround its orifice to receive the threaded collar 1), to which areattached the supportingarms c of the deflecting plate or disk (1, whichis thus held in the path of the stream of water issuing from the nozzle,at a short distance in front of the orifice of the said nozzle. The saiddeflecting-plate d is provided with a number of holes, 9, through whicha'portion of the stream that issues from the nozzle passes forward, asshown by the dotted lines 2, Fig. 1. The plate d has near its peripherywater-guiding faces h i is, curved at different angles relative to theaXis of the stream issuing from the nozzle, the'portions it beingcontinuations of the curvature of the main surface of the plate. Thewater striking on the surface of the said plate passes off tangentiallyfrom the different guiding-surfaces h i k at different angles, asindicated by the dotted lines 3, Fig. 1, a portion coming back towardthe hosenozzle, and a portion passing off at about right anglesthereto,so that the water is spread over a large area, thereby wettin gthe under side of the roof or floor adjacent to the point where thehose-nozzle is inserted, and thus extinguishing the tire and renderingit safe for the firemen to enter the building. The face of the plate 01is also provided with deflecting projections m, by which a small portionof the water is thrown back, as shown by the dotted lines 4, Fig. 1,directly toward the nozzle and hose, thus keeping its outer surface wetand cool and preventing it from being burned.

It will be seen that by raising or lowering the nozzle through theopening the water issuing from the different surfaces 72, t, and It willstrike the surface of the roof or floor at different distances from theorifice of the hose, so that the said surfaces will be thoroughly wetnear to and at a considerable distance from the hose. The water issuingfrom the surfaces It strikes the roof comparatively near the point wherethe hose is inserted, while that issuing from the surfaces It will passnearly parallel with the wall to as great a dis tance as the velocity ofthe water will carry it, and that issuing from the surface 1 strikes atintermediate points.

I claim 1. The waterdeflecting plate having cut therein on its underside the guiding-grooves h z k, of different depths and curvatures, eX-tending to the periphery of the said plate, combined with the arm a, tosupport the said plate across the path of the stream issuing froma hoseor pipe, whereby the said stream is thrown at different angles withrelation to the direction of the issuance of the stream, as set forth.

2. A Water deflect-ing plate having out therein the grooves h z k, ofdifferent depths and curvatures, combined with the projections in andarms 0, to support the said deflectingplate across the path of a streamfrom a hose or. pipe, substantially as shown, and for the purposedescribed.

8. A water deflecting plate having cut therein the grooves h ilk, ofdifferent depths and curvatures, and the holes e, combined with theprojection in and arms 0, to support the said deflecting-plate acrossthe path of the stream issuing from the hose or pipe, substantially asand for the purpose described.

In testimony whereof Ihave signed my name to this specification in thepresence of two subscribing witnesses.
